Title: Improvements in scoring devices for games
IPC: A63B71/06
Filed: 1937-06-17
Abstract: 497,401. Games - scoring devices. GEORGE, J. W., and BAYFIELD, A. H. June 17, 1937, No. 16893. [Class 132 (ii)] A scoring device for two players particularly applicable to the game of darts, consists of four counters 3, two for each player, engageable with two gear wheels 8, the arrangement being such that the counters of one player only are engaged with the gear wheels at a time. The gear wheels 8 are freely rotatable on a shaft 5 and each carries a ratchet wheel 1, the teeth of which are oppositely directed and engaged by pawls carried by an arm 4 keyed to the shaft 5 which can be rotated by a pointer 6 moving over a scoring dial 7. Movement of the pointer in a clockwise direction actuates one counter and an anticlockwise movement actuates the other counter. The counters are connected by bevel wheels with square spindles 9 on which slide pinions 3a connected to a key 13 movable across a gate 13B. In order to print the scores made, two rolls 12 of strip paper, one for each player, are carried by a sliding carriage 12c which is connected to the key 13 so that the crosswise movement of the key in the gate 13B moves the carriage to place one paper strip over a type wheel 11 fixed to the shaft 5. A carbon ribbon 11a is located between the strip and the type wheel. The strip 12 is pressed upon the type wheel by a type key 12D which is connected to the key 13 so that downward movement of the latter in the vertical parts of the gate 13B causes a downward movement of the type key. The strip is fed by feed rollers 12E actuated by the type key through a ratchet lever 12F. In a modification, two pinions are permanently engaged with the gear wheels 8 and the counters are connected to the gear wheels by clutches actuated by the crosswise movement of the key 13.

Filed: 1976-04-27
Abstract: 1529397 Shutter speed indicator ASAHI KOGAKU KOGYO KK 27 April 1976 [2 May 1975] 16949/76 Heading G2A [Also in Division G4] A shutter speed indicator has light emitting diodes L1 to L16 with their anodes connected into groups, each group forming an external anode terminal, and their cathodes connected into different groups, each group forming an external cathode terminal. The arrangement is such that only one LED is connected between any given external anode terminal and any given external cathode terminal. A four bit binary counter (6), Fig. 3 (not shown) feeds an output indicative of shutter speed to a decoder 5 which applies a voltage across just one pair of external anode and cathode terminals to energize the appropriate LED L1 to L16. The arrangement has the advantage that the LED array has a small number of external terminals e.g. eight for sixteen LED's. As shown, the decoder 5 comprises AND-gates 14 to 17 and OR-gates 18 to 21 which receive signals direct from the outputs RSTU of the binary counter (6) and via inverters 10 to 13.

Filed: 1938-06-08
Abstract: 515,638. Casting hollow ingots. JONES, E. F. June 8, 1938, No. 17076. [Class 83 (i)] A hollow steel, ferrous alloy, or other metal body is made by pouring the metal into a mould 11 having an aperture in the bottom 12 through which a core 13 is advanced as the metal in the mould rises. The core is preferably tapered downwardly, to free itself from the solidified metal and may be cooled internally by air or other jets 15. The. core may be withdrawn upwardly or downwardly, in the latter case it must be made collapsable, e.g., as described in Specification 406,666. If pouring is continued after the core ceases to rise a hollow body closed at one end is produced. In a modification the core may have a detachable head so that this can be readily withdrawn upwardly or to permit replacement by a cooler head. The core may be arranged to carry a thin stainless steel or other metal casing which is left in the cast body as a lining. The cast body may be forged or otherwise brought to desired shape. To assure that the metal is poured at a constant rate a tundish as described in Specification 488,378 may be used. Specification 381,790 also is referred to.

Abstract: 1506498 Travelling wave shedding looms RUTI MACHINERY WORKS Ltd 24 April 1975 [24 April 1974] 17135/75 Heading DIE The bobbins of a travelling wave shedding loom shuttler are rewound as they pass around a curved track at the inlet side of the shed. The shuttles 4 are pushed by pegs 8 on a return chain 5 around a curved track 6, 7 having a rotatable gear wheel 11 which engages teeth on the periphery of the bobbins in the shuttles. As the shuttles enter the curved track a yarn guide tube 30 is pivoted to place a weft 35 held in a clamp 40 over the path of the shuttle and a presenter 50 is depressed to engage the weft so that continued movement of the shuttle jams the weft in the spool. The clamp 40 is then released and the chain 5 moves the shuttle around the track whilst the wheel 11 winds weft onto the bobbin. At the exit from the track the weft again enters the clamp 40 which closes to grip the weft which is subsequently severed by shears 61 between the clamp 40 and shuttle 4.

Abstract: 407,330. Spring hammers. MEISSNER, F. E., 36, Avenue de la RochetaillÚe, St.- Etienne, Loire, France. Aug. 2, 1932, No. 17220/33. Divided application. [Class 124.] Spring hammer comprises a box 7 guided by surfaces 9 in the front part 8 of the casing and reciprocated by a crank 5 driven by a flexible shaft through gearing 2, 3. A ram 21 is mounted between springs 18, 19 in the box 7 ; an inwardly turned sleeve 13 on the casing is divided into four bars 24 which pass through the flange of the ram to guide the latter ; beads 29 on the ram minimise friction with the box 7 and exclude dirt. A tool 27 is removably mounted in the sleeve 13. In order to eliminate recoil, the following relation between the elastic and kinematic characteristics of the hammer pasts and the rebound ratio is satisfied, viz.:- where # is the rebound ratio of the ram on the tool, obtained by experiment, r is the radius of the crank, xa is the stroke of the ram between its neutral position at no-load and its position at the moment of impact with the tool, # is the angular velocity of the crank, and # is the angular speed of an imaginary point moving along an imaginary circumference so that its projection on a straight line would have the same vibratory movement as the free end of the spring means. # is equal to #K/m where K is the constant of the elastic system, i.e. the force necessary to move the ram through unit distance against the resistance of the springs, and m being the effective mass of the parts participating in the oscillation. Reference has been directed by the Comptroller to Specification 391,099.

Title: Clutch assembly
IPC: F16D67/00
Filed: 1973-04-06
Abstract: 1425699 Friction couplings; variable-speed gearing; spot-type disc brakes H STIRLAND 6 April 1973 17400/75 Divided out of 1415523 Headings F2D F2E and F2U A hub 112 is restrained against rotation relatively to a housing 200 by co-operation between rollers 104, 105, 106, (107) carried by the hub and pressure plates 180, 184 mounted in the housing and pressed towards each other into engagement with the rollers by adjustable springs 136. The rollers are rotatable on shafts 108, 109, 110, (111) which extend radially from the hub so that two diametrically opposite rollers 104, 105 coact with one plate 180, and the other two diametrically opposite rollers 106, (107) coact with the other plate 184. The housing 200, together with the plates 180, 184, is held against rotation by a brake (not shown). The plates have facings 121, 123 of brake lining material or a resilient, deformable material, e.g. rubber, so that rotation of the hub necessitates deformation of the facing material. As described, the apparatus acts to restrain rotation of a planet carrier 13 of an epicyclic transmission gearing comprising a gear 21 attached to an input shaft 11, a gear 18 fixed to an output shaft 12, and intermeshing planetary pinions 19, 20 in mesh respectively with the gears 18, 21. The hub 112 is fixed to an extension 17 of the planet carrier which is thereby held against rotation until a predetermined torque on the output shaft, determined by the adjustment of the springs 136, is exceeded. A neutral condition of the transmission is obtained by release of the brake holding the housing 200.

Abstract: 334,600. Lorenz Akt.-Ges., C. Jan. 24, 1929, [Convention date]. Directive signalling to and from ships.- Short - wave radio transmitters are installed in place of the usual port, starboard, and masthead lights particularly for navigating a ship in foggy weather. The wavelength used is preferably of the order of one metre, the spread of the radiation being confined within the necessary angles by means of parabolic or similar reflectors, whilst the effective, range is determined by the height of the transmitter above sea-level. The position, as distinct from the bearings, of an oncoming ship may also be determined by using a receiver in combination with a rotatable directive screen, such as 4. The radiation area of the masthead transmitter T is shown by the circle T<1>, and that of the port and starboard installations by the arcs Band St respectively. The transmitters are combined with similar shortwave receivers, which may also serve to sound an alarm should any transmitter fail to radiate. Each transmitter may radiate a characteristic , morse signal. The whole signalling system is controlled from the bridge of the ship. Specifications 279,821, 329,812, 330,750 and 338,028 are referred to.
